Unable to view values of variables while debugging

Question

I'm trying to debug portions of the current application I'm working on, however when I try and check the value of a property/variable I get the error:

Cannot evaluate expression because a thread is stopped at a point where garbage collection is impossible, possibly because the code is optimized.

This is just a regular ASP.NET project. In some portions of the application I can view the properties and variables perfectly fine. I haven't figured out what's different about the blocks of code that I can and can not see the values of the variables in.

Answer 1

The problem was documented on an MSDN blog, as being a size limitation of certain types in certain situations, more details in the link. I believe it was 256 bytes and/or the total size/count of the number of arguments passed to a function. Sorry to say there does not seem to be a quick fix, but hopefully the MSDN blog entry will help you identify a way to solve your problem.

Answer 2

This article, Rules of Funceval gives a number of reasons why this can occur. If debugging is turned on and optimisation turned off already, there doesn't seem to be much else you can do about this problem.
